Removing the gearmotor
Before installing a new geared motor, it is necessary to adjust it (set it to the end position f), for this:
- - connect the wiring harness block to the gearmotor;
- - put the gearmotor in the opening of the air intake box;
- - connect the wire to the negative terminal of the battery
- - turn on the ignition;
- - turn on the windshield wiper in the working position for 1-20 seconds and then turn it off - the gearmotor will be set to the extreme end position
After that, install the gearmotor and all the parts in reverse order.
